In cataract patients and sometimes in patients with high glasses without cataracts, treatment is carried out by removing the lens in the eye and replacing it with an artificial lens.
This artificial lens, which is placed in the eye, continues to exist in the eye throughout the life of the person.
When a single-focus lens is inserted into the eye, the patient can see far away without glasses, but it is not possible to read closely without glasses.
In order to read the book, newspaper, he must wear close glasses. When a multifocal lens is attached, the patient sees far and near without glasses, but the intermediate distance, that is, the distance between 40 cm and 2 meters, cannot be seen clearly.
Trifocal lenses are threefocused and the lenses that solve this problem.
When this lens is attached, the patient can see far, near and intermediate distance (between 40 cm and 2 meters) without glasses. For example, the quality of vision is good when using a computer.
These lenses can be used in people who have cataract surgery. People who do not have cataracts but who wear high glasses can also perform this surgery to get rid of far and near glasses.
In which eye problems can tTRIFOCAL LENSES be used?
“The most important use of trifocal lenses is cataracts.”
Because in cataract surgery, the lens inside the eye is removed; the capsule remains. A lens must be placed inside this capsule.
That lens is just a single-focus lens that corrects the distance; It can be the lens that corrects astigmatism or the lens that sees distance, near, middle distance and astigmatism.
Secondly, if the patient has a near vision problem, the near and far vision can be corrected at the same time. This can also be applied to people over 45-50 years old or those who only have close vision problems.
“These patients will not have cataract problems in their future lives. ”
